Introduction to Statistics

"Welcome back to School! Wish everyone in the new semester
More happiness! More Health! More Bright Future!"
-- Dr K

• How Hot is Statistics/Big Data now:
Statistics/Big Data is like teenage sex
Everyone talks about it
Nobody really knows how to do it
Everyone thinks everyone else is doing it
So everyone claims they are doing it....

For the textbooks of statistics, there are usually two classic textbooks:

1. Elementary Statistics, 3rd CA Edition, by Triola, Pearson.

2. Elementary Statistics: A Step By Step Approach 12th Edition by Allan G. Bluman.

The following are the amazon links for the textbook and student solution manual. You may consider buying together with other classmates if it's expensive.

Shopping Tips: Don't buy stuff for cheap, eventually it will cost you more.
  How can you get some cash back when you shop online?
Say, you want to buy some grocery from target online(3% cash back), or buy a ipad from apple store(1% cash back), this website Mr. Rebates provides you the link to those online stores, with exactly the same price; meanwhile, you can get some cash back(2%-20%) for the purchase.

That means, when you want to buy something online, don't go to their site directly, but go to this site Mr. Rebates first, then find the website on Mr. Rebates that you want to go , buy stuff through that link, then you will get some cash back from the purchase. This can help you earn a few hundred dollars per year easily.
